Learn the 3 easy steps to Block Unc0ver Jailbreak Tool in iOS apps, to prevent hackers from Jailbreaking iOS apps.
Unc0ver is a jailbreak tool used to take control over the iOS operating system (ie: to Jailbreak iOS). Unc0ver is a ‘semi-tethered’ jailbreak tool, in that it allows for the iOS device to reboot on its own. On each boot, the iOS device startup sequence is modified and is booted into its original, non-jailbroken state. If the owner wishes to jailbreak their device again, they can do so with the help of an app running on the iOS device.
Semi-tethered Jailbreak tools (i.e. Checkra1n) will be installed using a computer attached via USB to the iDevice. These tools usually come with on-screen prompts to guide the user through the various steps (like which buttons to press, based on the specific iDevice type) to reach the “Device Firmware Update” mode (DFU), which is required in order to execute the jailbreak.
Jailbreaking is the process of unlocking the iOS operating system on an Apple mobile device. Jailbreaking is a form of administrative privilege escalation, which bypasses Apple’s restrictions, resulting in full administrative control over the OS (the highest level of administrative privilege possible). Jailbreaking is often accomplished by exploiting bugs in Apple’s software/firmware or modifying system kernels to allow read and write access to the file system. Jailbreaking is one of the primary methods/tools for every hacker – both black hat hackers and white hat hackers (eg: penetration testers or security researchers). They all use Jailbreaking in similar ways (to compromise the security model of mobile devices, the operating system, and any app running on the device). The main difference is that black hat hackers have malicious intent, while white-hat hackers generally have non-malicious intent.
Whatever the intent, Jailbreaking makes every hacker’s job much easier by providing a significant advantage to compromise the security model, due to the elevated level of privilege and full administrative control that Jailbreaking enables. Jailbreaking makes it easier to disable anti-tampering protections, to disable security protections, to make changes to the iOS file system, to change properties files, bundle ID’s or other app attributes (eg: hackers sometimes jailbreak iPhones to bypass in-app purchases, or for hacking info.plist to turn off mobile advertisements inside the app, just to name a couple of examples).
Net net: Jailbreaking compromises the mobile security model. Any iOS app that runs on a Jailbroken device is in a vulnerable state, where hackers can amplify and increase the magnitude of their attacks. And when iOS apps run on Jailbroken devices, you really can’t trust any of the signals, messages, or behaviors associated with the device (or anything running on the device).
Keep reading to learn how to use Appdome Jailbreak Prevention to protect any iOS app against Unc0ver and many other Jailbreaking tools.
Appdome Jailbreak Prevention enables an iOS app to protect itself against Jailbreaking and Jailbreaking tools like Unc0ver. You can use Appdome to build Jailbreak Prevention into any iOS app – without coding. When the Appdome-secured app detects that it’s running on a Jailbroken device the app will shut itself down (default behavior) after displaying a message to the mobile user. This protects that app, user, and mobile data from being compromised or attacked by a malicious actor using Jailbreaking.
Please follow these 3 easy steps to Block Unc0ver in any iOS app to prevent hackers from compromising the app’s security model.
Congratulations! The app can now defend itself against Jailbreaking and Jailbreaking tools like Unc0ver.
Appdome’s no-code mobile app security platform offers mobile developers, DevSec and security professionals a convenient and reliable way to protect Android and iOS apps with RASP (Runtime Application Self-Protection), such as Jailbreak Prevention. When an Appdome user clicks “Build My App,” Appdome leverages a microservice architecture filled with 1000s of security plugins, and an adaptive code generation engine that matches the correct required plugins to the development environment, frameworks, and methods in each app.
